Summary: I have several Twelve South products, and have been 110% pleased with them. This is obviously not a high end sub, and I didn't expect it to rattle the room. However, after trying several songs and listening to it for a while, I was incredibly disappointed. It virtually produces no sound.
Summary: Seems to change the key of the music in iTunes to something other than what is correct, as well as adds a nice amount of static to the audio. Perhaps a software related issue, but as it is right now, this product is entirely unusable on my 5k iMac.
Excerpt: brings a fuller not louder sound to my MacBook Pro I was disappointed at the condition the packaging.looks like it was sitting on the shelf for a few years the corners of the package were damaged but not the unit itself.
Excerpt: For a compact, portable unit the BassJump adds some much needed depth to the sound of my MacBook And iMac. Download the software, plug it in & play...it's literally that simple. Even the product packaging was really nice! Quite a deal for around $ bucks.
Yosemite was released 10/16/14 STILL NO UPDATE...ITS USELESS!!

Summary: The sound was decent until the connection to the box stopped working periodically. Then after upgrading my Mac to Yosemite it became as useless as a truckload of dead rats in a tampon factory.
Summary: Not bad. Some weird quirks; unit will randomly produce an audible 'thump' once USB power is removed. I can only guess that is the result of the capacitor[s] de-energizing. This is not a sub-woofer. Rather, bass augmentation for lacking PC speakers.
